Birbara, P J; Genovese, J E

A system is described for catalytically oxidizing aqueous organic contaminants, comprising: (a) means for heating a reactor feed stream containing aqueous organic contaminants to a desired reaction temperature; (b) means for oxygenating the reactor feed stream; (c) a catalyst bed capable of completely oxidizing the aqueous organic contaminants in the reactor feed stream at temperatures of about 300 F or lower and a pressure sufficient to keep the reactor feed stream in the liquid phase to produce a substantially contaminant-free reactor effluent stream, wherein the catalyst bed includes a catalyst having about 5 wt % to about 20 wt % noble metal crystallites about 100 [angstrom] or smaller in size selected from the group consisting of platinum, palladium, ruthenium, iridium, and combinations thereof deposited on a high surface area catalyst support and the catalyst bed is sized to provide a liquid residence time of less than about 5 minutes, resulting in reduced system volume, weight, and energy consumption: (d) means for contacting the reactor feed stream with the catalyst bed; and (e) a phase separator for separating gaseous reaction products from the reactor effluent stream.
